Abstract

The dielectric constant of gold nanoparticle is size dependent, resulting in the distinct optical properties. Therefore its scattering or absorption spectra can be used to determine the size of the gold nanoparticle based on the Dipole theory. Current size quantification methods include second-order scattering, dynamic light scattering, SEM, TEM, and etc [1]. However, these methods require either tedious post processing or bulk and expensive equipment. Here, we propose a fast and simple optofluidic chip for the trapping and characterization of single 60-nm gold nanoparticle using optical forces in the light-sheet optical chromatography.
